Mutual information (MI) quantifies neural responses by decomposing variability, offering a clearer understanding of its measurement and calculation challenges. This study clarifies its reliable use in auditory neuroscience.

Area of Science:

  • Neuroscience
  • Information Theory
  • Auditory Neuroscience

Background:

  • Mutual Information (MI) is increasingly used to quantify neural responses.
  • Researchers express doubts regarding MI's precise measurement and practical calculation difficulties.

Purpose of the Study:

  • To clarify the interpretation and calculation of Mutual Information (MI).
  • To establish guidelines for the informative and reliable application of information theory in auditory neuroscience.

Main Methods:

  • Interpreting Mutual Information (MI) as a form of variability decomposition, analogous to variance decomposition.
  • Analyzing the computational challenges associated with calculating MI.

Main Results:

  • Mutual Information (MI) can be understood as entropy-based variability decomposition.
